Review on 🖱️ Logitech MX Master Wireless Mouse: High-Precision Sensor, Easy-Switch up to 3 devices, Meteorite Black by Keisuke Uemura ᠌

This mouse has a very noticeable "hump" on the left side, above the horizontal scroll bar. In reality, it is larger than it seems in the photo. Apparently, you need to hold the mouse like a trackball. I honestly tried to get used to it, I tried to change the grip in different ways. But after about three days, unpleasant sensations appeared in the hand, which began to intensify. Then several very strong and painful spasms occurred in the palm of the hand exactly in the place where the "hump" of the mouse falls - the junction of the thumb and palm. With such problems, I can not use the mouse, and frankly, I do not know what to do next. It is very unfortunate that this happened. I advise you not to choose a mouse from the photo, but to go and thoroughly touch it with your hands, especially if you have a large palm with long fingers, like mine. Mouse changed from Razer Naga Hex after six years of use. If the double click hadn't appeared, I would have used it that way. :)
